## What it is
Deku is a JavaScript library for rendering user interfaces using pure functions and a virtual DOM, designed as a lightweight alternative to React. It delegates all state management and side effects to external tools like Redux and ships modules for element creation, diffing, DOM rendering, and string rendering.

## Use cases
- render ui with pure functions and virtual dom
- build stateless components without classes
- use a lightweight alternative to react
- render virtual elements to an html string
- build a custom renderer using a virtual dom diff

## When to choose
- you want a minimal, functional, class-free ui library
- your app already uses redux for all state and side effects
- you only need to support modern browsers

## When to avoid
- you need an actively maintained library with ongoing fixes
- you need broad legacy browser support
- you want a large ecosystem and community like react

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, frontend-framework, state-management
- domain: web-development, frontend
- platform: browser
- tags: virtual-dom, react-alternative, redux, functional-ui, jsx, nodejs, javascript
